I’d love to see the addition of “deep rough” areas with a 20% penalty to make course layouts more enjoyable and realistic.
Currently, courses without trees, sand, or water hazards often end up as one large area of 10% rough, which makes links-style courses feel less interesting and challenging. Adding deep rough zones would introduce more strategic play and variety.
Some of my favourite courses are those surrounded by sand, where you have a mix of 10% rough and 20% sand penalties. If deep rough could be implemented in a similar way, it would really enhance the experience and make links courses more engaging.
